*Use carton (not canned) unsweetened coconut milk in place of the unsweetened almond milk for a nut free version. Most people with nut allergies can have coconut, but check with your doctor first to make sure.
**Feel free to add more peppermint extract if you like (especially if you don't have any sugar-free peppermints to add to the frappe). I try not to add too much peppermint extract because it leaves a sharp taste.
***I just put the chocolate and peppermints in the blender whole and let them blend with everything else so they blended pretty fine, but if you want bigger, get-stuck-in-the-straw chunks, blend the frappe, then add the chocolate and peppermints and pulse to get the size chunks you want.
